I just purchased a case of black cloud snow goose loads which are 1635fps. I bought a patternmaster black cloud choke tube. which until I got package does it say not reccomended to shoot over a 1550 fps load! reason is it breaks up pattern? . Just wondering if anyone has had an issue with this type of combination even the carlson says not higher then 1550 in there black cloud tube. I am shooting a MAXUS. the shells are 3" bb and choke is full. Thoughts!? heading out saturday! Thanks all and good luck out there! after talking to patternmaster they are changing there website to reflect this disclousure.
